There is a lot of excitement for #offshore #wind but it still needs innovation to become cost competitive.

@thomas offshore wind is cheaper than onshore and solar in the UK. Adoption rates will presumably brings offshore costs down in the US.

@pauleastwood very cool.

Are those years at the top? I am not sure I understand your chart though. Is it saying that in '26/'27 offshore is expected to be £37.35 £/MWh? I would like to see more information.

I am in California where they just opened the north coast for Offshore wind. Our sea floor is... not as fun.

@thomas yes, sorry, not an easy table to follow without some explanation. Here's a good article that should help. The columns are years when the contracts are expected to start operating. The plants haven't yet been built.

Analysis: Record-low price for UK offshore wind is nine times cheaper than gas - Carbon Brief

This is the UK’s fourth biannual “contracts for difference” (CfD) auction round (AR4). As well as seeing record-low prices, with 11GW of capacity secured, it is also by far the largest.

@thomas and here are the full details to accompany the data. The table is from 'Auction results'.

@pauleastwood Thank you.

Do you know/think those prices also reflecting subsidies for building Offshore wind?

@thomas depends on the market price for electricity. If this is lower than the prices set at auction (those in the table) then the generators receive a top-up to the market price. If the market price is higher, the generators pay back the difference. With the current high prices for electricity in the UK, the generators would not receive a subsidy if they were operating today.

The system is a little complicated but nicely explained in the article I linked to.
